“Waking a sleepwalker is dangerous.”

The idea that waking a sleepwalker is dangerous, leading to severe health consequences like a heart attack or brain damage, is a widespread misconception. In reality, rousing someone from a sleepwalking episode is generally not physically harmful to them. While they might experience temporary confusion, disorientation, or even agitation upon waking, there's no scientific evidence to support the dramatic claims of serious physical harm.

This enduring myth likely stems from ancient beliefs and a lack of understanding about sleep. Historically, some cultures believed that the soul left the body during sleep, and waking a sleepwalker would leave them "soulless" or cause psychological damage. Over time, these fears evolved into exaggerated warnings about physical harm, perpetuated by old wives' tales and dramatic portrayals in popular media.

The scientific explanation clarifies that sleepwalking occurs when a person is in a state between deep sleep and full wakefulness. When abruptly awakened from this deep sleep, it can trigger a startle response, leading to confusion, fear, or anxiety. This disorientation is why experts advise against forceful awakening, as the sleepwalker could lash out defensively or injure themselves by stumbling. However, the actual danger lies not in the act of waking itself, but in the potential for the sleepwalker to injure themselves by falling or bumping into objects if left to wander unsupervised.

Therefore, if you encounter a sleepwalker, the safest and most recommended approach is to gently guide them back to bed without attempting to startle them awake. If waking them becomes necessary due to immediate danger, do so gently by calling their name and reassuring them. Prioritizing the sleepwalker's safety from physical injury as they navigate their environment is paramount.
